Truth Teller is a way to fact check what politicians say, as they say it. When you watch a Truth Teller video on PostTV, you’ll see a transcript rolling next to it. When Truth Teller spots a false claim that we’ve reported on, a visual clue and a link to a full fact-check will appear. This is where you get the full story of what was just said, as provided by our Fact Checker blog, run by Glenn Kessler, as well as from Politifact and FactCheck.org.
Why are we in beta? Because instant fact-checking is a difficult thing to do. The different components that make Truth Teller run are new products. Natural language processing lets us process language as data, but we have to keep teaching our algorithm what constitutes a ‘false claim’ and how the same statement could be said other ways. And automatic speech recognition is still in early stages of widespread use, so you might see some head-scratching transcription errors. At this stage, we are augmenting this technology with Post reporters and editors to be certain that Truth Teller is accurate. These components are all moving along towards the long-term vision: a tool that can give you the reporting most relevant to what you’re hearing, at the moment you encounter a political lie.
